Tests run: September 30 – October 3, 2026 Games: Klondike, FreeCell and Spider Solitaire


A hint should help you win. Ours did not. In September we tested the Hint button in our three main solitaire games. We dealt 1,300 numbered games and played only the move the hint showed, every time. The hint won none of them.

This month we replaced it. The new hint takes its moves from a solver, the same kind of program that checks whether a deal can be won. Played the same way in our tests, it won 171 of 200 Klondike Draw 1 deals.

Here is what we measured, what changed, and how to use it.


How We Tested the Old Hint

The test is simple. Deal a numbered game. Press Hint. Play exactly the move it shows. Repeat until the game is won, the hint has nothing to offer, or the board repeats itself. A repeated board means a loop: the hint is sending you round in circles.

GameDealsWonEnded in a loop
Klondike, Draw 12000200
Klondike, Draw 32000200
Spider, 1, 2 or 4 suits200 each0600
FreeCell3000282

The loops began early: after 19.5 moves on average in Klondike Draw 1, 17.1 in Draw 3, 8.8 in Spider and 9.0 in FreeCell. The other 18 FreeCell games ended with the hint silent. It had filled all four free cells and had nothing left to say.

A loop usually took two moves. In Klondike deal 2, the hint moved the 3♠ onto the 4♦, which turned over a card. Next it moved the same 3♠ onto the 4♥, which changed nothing. Then it moved it back onto the 4♦, and the board repeated.

The deals were not the problem. Our solver proves 169 of the 200 Draw 1 deals winnable. In 152 deals, the board where the hint started to loop could still be won.

Why it failed

The old hint showed the first legal move from a fixed list. A legal move is not always a useful one. The hint had no memory, so it could undo its own advice. It offered the stock only when no other move existed. When it found no move at all, the button did nothing.

The look did not help either. The card to move and its destination wore the same yellow ring. A copy of the card flew across and covered the destination for a moment, and there were no words. On a phone, where the two cards often sit side by side, you could not tell which one should move. The picture at the top shows the first hint of the same deal in the old game and the new one.


What the New Hint Does

When you press Hint, a solver searches in the background for up to a second. In Spider it searches for up to a second and a half.

A Klondike hint: a gold ring on the 10 of clubs, a blue ring on the jack of hearts, an arrow between them, and the sentence 'Move 10♣ onto J♥. It turns over a hidden card.'
A Klondike hint: the card to move, where it goes, and one sentence that says why.

What you see:

  1. A gold ring on the card to move.
  2. A blue ring on the card or space where it goes.
  3. A faint copy of the card where it will land, and an arrow.
  4. One sentence: what to do, and why it helps.
  5. An Another move button, for the next useful move if you want a choice.

The hint stays for 8 seconds, or until you move. Tap the gold card to play the move, or press the H key for a hint. A hint costs no points. In Klondike, if you turn off the Solver setting, the hint still gives moves, but it never speaks of winning or losing.

The Results

Chart of games won by playing only the hinted move. The old hint won 0 in every mode. The new hint won 171 of 200 Klondike Draw 1 deals, 149 of 200 Draw 3, and 20, 19 and 10 of 20 Spider deals with 1, 2 and 4 suits.

Klondike. In Draw 1, the hint won every deal our solver proves winnable within 5 seconds (169 of 169), and 2 deals the solver could not decide. In Draw 3, it won 147 of the 151 deals proven winnable, and 2 more. These numbers come from our design tests: a model of the game that uses the game’s solver and the same one-second search per press.

Spider. These are deals 1 to 20 of each mode, played on October 3, 2026, under the standard rule: only a run of one suit moves as a unit. Four suits is still hard, and the hint won 10 of 20. The tests searched 200,000 positions per press. A fast computer searches more than that in a second and a half, and a slower device searches fewer. So the Spider hint depends on your device. On the first six 4-suit deals, 40,000 positions per press won 3 deals, and 200,000 won 5.

FreeCell. FreeCell is not in the chart, because our large FreeCell test counted deals the solver solves, not games won by following the hint. The solver solves 1,999 of 2,000 test deals, half of them in 2.2 milliseconds or less. In the game’s own tests and in our live check below, following the hint won every FreeCell deal it played. FreeCell shows every card, so its solver knows only what you can see.

In Klondike and Spider, the solver also knows the face-down cards. That is how it can prove a deal winnable. The hint never shows you those cards. It shows only the next move.


We Also Played the Real Game

The numbers above come from test programs. On October 3, 2026, we also played the live game in a web browser. A script pressed Hint, tapped the gold card, and repeated until the game ended.

GameDealsWon by the hintHow the others ended
Klondike, Draw 11–20155 at the recovery panel

Spider, 1 suit1–55—
Spider, 2 suits1–54, and deal 4 on one of three runssee below
Spider, 4 suits1–541 at “No useful move is left”

In Klondike, the hint won every deal that the game’s own check proved winnable: 15 of 15 in Draw 1, and 8 of 8 in Draw 3. Of the other seven deals, five were proved lost and the check could not decide two. All seven ended at the recovery panel. On four of the five lost deals, the hint first offered a few more moves, 2 to 17. We fixed that the same day: once the check has proved a deal lost, the first press of Hint opens the panel.

One 2-suit Spider deal, deal 4, gave three different results in three runs. On the first, one press of Hint just after a suit was completed showed nothing, and the script stopped. On the second, with longer pauses between moves, the hint won. On the third, from move 107 the hint moved the same few cards from column to column, and no suit was completed by move 160, where the script stopped. We fixed both faults the same day. A press of Hint now waits until a completed suit has landed. And the Spider solver now counts two boards that differ only in the order of their columns as one board, so its line never comes back to a board it has passed. Then we played 2-suit deals 1 to 5 again, and the hint won all five. It won deal 4 in 169 moves, at normal speed and with reduced motion, and no board came back. The same change made the Spider search about four times as fast, so each press now searches about four times as many positions.

The Klondike recovery panel after a losing move: No solution found from this position, with Undo to Last Winnable (1 move), Undo Last Move, Play Again, Deal Winnable, Show a Move Anyway and Dismiss
When its search proves a Klondike game lost, the hint opens this panel instead of offering a move.
